While you know for sure that you can report 91110 and 91111 for capsule study, but knowing just that is not enough to prevent your claims from being denied. We’ll tell you just when it is appropriate to report them  and which modifiers to append.

Reporting a Repeat Procedure with 91110

Sometimes, your gastroenterologist would use a capsule study to image the intraluminal esophagus all the way through the ileum and reaching the colon. In this case, you should report 91110 (Gastrointestinal tract imaging, intraluminal [e.g., capsule endoscopy], esophagus through ileum, with physician interpretation and report).

Let’s take an example. Patient comes in for a capsule endoscopy, but the capsule gets stuck in foodon hour five and visuals cannot be seen past the stomach. The gastroenterologist ends up repeating the procedure to see if she can see the small and large intestine.

First, you would code 91110 and then attach modifier 53 (Discontinued procedure) to indicate that the physician repeated the procedure. If the physician decides not to repeat the procedure, you should append modifier 52 (Reduced services) to reflect that the capsule imaged the patient’s anatomy until it became lodged in the food.

If you plan on repeating a capsule study due to technical problems, it is a good idea to pre-authorize payment for the second study with the carrier. You may need to provide records of the incomplete study.

CPT 91110’s descriptor clearly states the evaluation is from the esophagus to the ileum. The only time this won’t be true is when the gastroenterologist places the pill cam endoscopically for the study, says Joel V. Brill, MD, AGAF, chief medical officer at Predictive Health LLC in Phoenix. Again in this case, you should attach modifier 52 to 91110.
